Attorney General Jeff Sessions announced on Monday that President Trump would make defensive gear available to police again by undoing a policy from the Obama administration. Trump then signed an executive order whose title emphasized that branding: “Restoring State, Tribal, and Local Law Enforcement’s Access to Life-Saving Equipment and Resources.”

To the contrary of former New York City Mayor Rudy Giuliani’s claim at the 2016 Republican National Convention, police don’t always “just come to save you.” Here are 10 times police killed the very people they were called to help.

“I would do stop-and-frisk. I think you have to,” Trump said, according to excerpts of a Fox News “town hall” in Cleveland, after a listener asked what he would do to reduce crime in predominantly black communities across the nation. “I see what’s going on here, I see what’s going on in Chicago, I think stop-and-frisk. In New York City it was so incredible, the way it worked,” he added.

Over the last decade, collecting DNA from people who are not charged with — or even suspected of — any particular crime has become an increasingly routine practice for police in smaller cities not only in Florida, but in Connecticut, Pennsylvania and North Carolina as well.

Slow down, buckle up and take special care around fighting family members. Sounds like wisdom a parent might bestow. But, in layman’s terms, those are the recommendations of a new study of law enforcement deaths while on duty. In short, police will be more likely to return home safely after their shifts if more of them wear seat belts, take more care when racing to high-priority calls, wear their issued body armor and remember that calls involving domestic disturbances are often the most dangerous.

It was another traffic stop. Philando Castile was driving with his girlfriend, Lavish Reynolds, when they were pulled over at a traffic stop for a broken taillight, according to a video Reynolds posted on Facebook just after he was shot.

Paul Figueroa had briefly replaced Ben Fairow, whose tenure as Oakland’s top cop lasted just six days. Fairow had been appointed to replace Chief Sean Whent, who resigned in the wake of a widening sexual misconduct scandal.

In a surprise announcement Thursday afternoon, Mayor Ed Lee said that after the latest fatal shooting, of an unarmed woman in a suspected stolen car in the city’s Bayview neighborhood, he had lost faith that Suhr could mend the department’s relationship with the community.

In their training, Chicago police officers are presented with scenarios in which they’re confronted by dangerous individuals while other people are nearby. The goal is to eliminate the threat while keeping bystanders safe. Yet over the years, innocent victims have been shot by police.

Many rank-and-file officers and their superiors have assumed the mantle of victims, complaining that the Black Lives Matter movement disrespects, and even endangers, police. It keeps them from doing their jobs, they say.

Even with the best training, studies show that police have a very hard time hitting their intended targets. New York City’s Police Department has some of the best-trained officers in the country. But when 12 Brooklyn cops opened fire on a fleeing gunman last month, only one of 84 shots fired hit the suspect.
